1. You need to know the actual rating of any sub-section buss that you
will be backfeeding with PV. Do not backfeed this buss with more than
100% of it's ampacity.
2. Evaluate 120% of the 4000A buss against the 3500A main and all PV
backfeed all of the subsections.

Hi john
What you are looking for on the brushes is
End bell brush kit. $27
But I highly recommend Sunpumps brand submersible pumps. Vastly superior
design, much easier to repair, and connecting the wires is super easy and won't
leak
On the overall pump design all these diaphragm pumps
Mark,
Thank you, your response is very helpful! How does the 120% rule get
applied to the 1000A sections in my example? When grid connecting
downstream on the load side of the switches on the 1000A sections do we ignore
the rating of the 1000A bus bar being protected by a 3500 Amp Fuse?
NEC 2008, 240.21 (B)(1)(1) a.
Each of the smaller buss sections are feeders which are sized according
to the tap rules. I believe the answer to your question is that the
larger fuse can't protect the smaller buss. *But*, the likelihood of a
short developing in that section of the circuit is
Wrenchers,
I run into lots of Service Equipment that has a Large Service Switch which
feeds multiple Sections with the Bus bar on each section rated significantly
less than the main bus.A specific example that I am currently looking at
has a 4000Amp Switch with a 3500 Amp Fuse which feeds 3

Gary,
We've had problems from time to time with toyostoves and other sensitive
electronics not liking the waveform coming from the inverter. 50 mcf,
what voltage? How is it wired? Is there a schematic and any other info
on the Magnum site for this fix?
Thanks!

Marco and all wrenches,
Thanks for the cost /benefit comparison on batteries. We need batteries
that won't freeze easily. Even if the cost was the same we'd need to
know more about the Aquions before we could risk installing them in the
North.
I need a fact check from someone on Lead
Thanks for the tips. Focused Energy is carrying the Poly 255 Yingli black
frame white backsheet. Conergy referred me to Soligent and they are not
carrying the Yingli brand. Rumor is the Panda mono from Yingli are not
available in the US. Can anyone confirm this rumor?

Greg--I've attached a link to East Penn Manufacturing (aka Deka or MK
Batteries) recycling brochure. They have the largest battery plant in the world
and recycle 200 million pounds of lead and 11 million pounds of plastic a year
in their battery production. We live near them and we're in an
I have in the past just removed the brushes and gone to a GOOD hardware store
of a starter alternator shop and found something similar and used sandpaper to
fit the brushes. The brush material is quite soft.
